A community is planning to build a rectangular garden. The width of the garden is 17 /4 feet (ft), and the perimeter of the gard
Lynna [10]

Answer:

34 square feet

Step-by-step explanation:

First, you need to find the other side of the garden in order to find the area a=l*w

The formula to find the length is, p-w*2=x x÷2=l

because, perimeter is l+l+w+w and area is just l*w

4.25*2=8.50

24.50-8.50=16

16÷2=8

l=8

So now we need to multiply the length and width to get the area.

8*4.25=34 sq. ft.

I hope that helps!

Answer:

Y=3x+5

Step-by-step explanation:

If we take x = 1, according to the first function (the answer) y would be 8.

Other options:

—————

Formula 3:

Y= 2^x+5 == 7

Formula 4:

Y = x+8 == 9

True answer = 10.

——————

Ok, so the last one seems more accurate lets test the first and last one on two more numbers:

——————

X = 15

Formula 1:

50

Formula 4:

23

True answer = 60.

The first formula wins.

————————-

X= 10

Formula 1:

35

Formula 4:

18

True answer = 41

The first formula wins.

——————

So, we can see that the first formula is most accurate.

A student concluded that the inequality -3+2y<4x is equivalent to the inequality y>2x+3/2, as shown below. Describe and co
svlad2 [7]

Step-by-step explanation:

-3+2y<4x

then

2y< 4x+ 3 (add both sides with 3)

y < 2x +3/2 ( divide both sides by 2 that is positif and we do not change the sens < )

Hope you understand.
